Our best offering in a fi berglass housing. The OTRS series pairs an incredibly durable housing with our excellent blades. End caps on the arms further protect the housing. We cover each blade with two coats of PVC protected by double shield, one to bind the fi berglass strands and a second over the printed units, so the numbers don?t wear away. The 3X high-speed rewind gearing is made up of metal, strip-proof gearing.
